Power Supply

The equipment is intended to operate with a power supply not to exceed 250 volts between phase and neutral or between phase and ground. A proper ground connection through the ground connector of the power cord is essential for safe operation.

Grounding the Generators

The generators are grounded through the power cord. To avoid electric shock, plug the power cord into a properly installed receptacle which was tested by a qualified electrician. Have the test performed before connecting equipment.

Without the protective ground connection, all parts of the generators are potential electric shock hazards. This may include components which appear to be insulated. The equipment MUST NOT BE USED if this protection is altered.

Use the Proper Power Cord

Use only power cords and connector specified for your product. Use only power cords in good condition.

Use Proper Fuses

To avoid fire hazard, use only fuses as specified in the parts listing for your product - matching type, voltage and current rating.

Do Not Remove Covers or Panels

To avoid personal injury, do not operate the generators without panels and covers.

Do Not Operate in an Explosive Environment Electric Overload

Never apply power to a connector which is not specified for that particular voltage/current.

CAUTION

Before using this equipment, read the user manual and the separate delivered safety manual carefully

1.3. Responsibility of the operator

These operating instructions form an essential part of the equipment and must be available to the operator at all times. The user must obey all safety instructions and warnings.

CAUTION

The purpose of this instrument is the generation of defined interferences signals for EMI immunity testing. Depending on the arrangement of the test rig, the configuration, the cabling and the properties of the EUT itself, a significant amount of electromagnetic radiation may result that could also affect other equipment and systems.

The equipment is designed to operate in industrial environment. For operating in other or sensitive environment, such as light industry, airport area…, the user may use a shielded room for operate.

The user himself or herself is ultimately responsible for the correct and controlled operation of the rig.

In case of doubt, the tests should be carried out in a Faraday cage.

1.4. General hazard

Before applying power to the system, verify that your product is configured properly for your particular application.

WARNING

The generators and their accessories operate at high voltages.

Hazardous voltages may be present when covers are removed. Qualified personnel must use extreme caution when servicing this equipment.

Circuit boards, test points, and output voltages also may be floating above (below) chassis ground.

The design of external insulation must be such that it exceeds the maximum impulse voltages of the generator (5.5 kV or 7.0 kV).

Only qualified personnel who deal with attendant hazards in impulse generators, are allowed to perform installation and servicing.

Ensure that the AC power line ground is connected properly to the Power Rack input connector or chassis. Similarly, other power ground lines including those to application and maintenance equipment must be grounded properly for both personnel and equipment safety.

Always ensure that facility AC input power is de-energized prior to connecting or disconnecting any cable.

The user must ensure that the output power lines are labeled properly as to the safety hazards and that any inadvertent contact with hazardous voltages is eliminated.

Guard against risks of electrical shock during open cover checks by not touching any portion of the electrical circuits. Even when power is off, capacitors may retain an electrical charge. Use safety glasses during open cover checks to avoid personal injury by any sudden component failure.

Neither AMETEK CTS GmbH, nor any of the subsidiary sales organizations can accept any responsibility for personnel,

material or inconsequential injury, loss or damage that results from improper use of the equipment and accessories.

Measuring instruments for the measurement of instrument parameters shall be designed for the maximum voltage and current from the generator. Otherwise safety cannot be guaranteed.

1.9. Procedure in case of hazard

If a hazard could exist due to an unintended condition of the generator, the following procedure is recommended:

Disconnect the device- and EUT power supplies from the power supply and ensure that the generator is always earthed via the supply lines or a different ground connection. Wait at least 15 minutes and ground all outputs via a 10 kΩ, 15 W resistor.

Call an AMETEK service center.

1.10. Temperatures at the surface

The components that generate heat in the device (resistors, etc.) are arranged inside the device in such a way that no temperatures higher than 50 °C occur on the surface.

1.11. Lifting and carrying instructions

The generators usually weigh more than 20 kg. For lifting and carrying, two persons must always lift the equipment together or

use a suitable lifting device. The device must be gripped by the carrying handle and on the underside.

2. Before Activating the Equipment 2.1. Damage due to Shipment

The instrument was tested before shipment and was packed carefully on a transport palette. Each box is marked with a detailed list of the contents.

Before activating the equipment, check for damage which may have occurred during shipment. Check each container as well as the generator itself. In case of physical damage, contact the manufacturer before operating the unit.

Figure 1 – Instrument

Figure 2 – Rack

Figure 3 - System

2.2. Power requirements

Prior to turning the equipment on, check that the selected voltage corresponds to the supply voltage.

The position of the voltage selector must correspond with the mains.

If you change the mains voltage, replace the fuses according the recommended value on the number plate.

First - check the 115 V / 230 V voltage selector where applicable!

Do not connect 230 VAC into the 115 VAC units.The result could be a severely damaged unit.

Figure 4 - Power Settings

If power to the equipment of Class I is supplied by an auto-transformer which is connected to a higher supply voltage, the base of the auto-transformer must be connected to the neutral of the power supply.

Equipment of Class I, which is supplied with a 3-phase power cord, must only be connected to a grounded receptacle. The protective ground connection must not be disconnected or otherwise interrupted.

Each interruption or disconnection of the protective ground connection inside or outside the equipment may cause electric shock.

Connecting different units with each other or to a personal computer for remote control may be performed only with cables

recommended and/or supplied by the manufacturer.

2.3. 3-phase EUT power lines

The connectors for 3-phase EUT power lines on the devices is realized with CEE connectors.

Please take care to connect carefully the correct plugs during installation.

Important is a direct connection between neutral and PE from the power supply. Otherwise you get problems with the floating neutral star point and inconvenience or malfunctions during the test.

The figures show the correct mapping of the plugs of the CEE connectors.

Figure 5 - Female Receptacle Figure 6 - Male Plug

2.4. Fuse for the EUT power supply

The pulse generators have no built in fuse for the EUT power supply. It is in the scope of responsibility of the user to protect the EUT external for the rated current.

CAUTION

The design of the external fuse must be matching the following rules:

fuse dimension must be equal or smaller than the rated EUT current of the connected test generator fuse must be designed for protect the connected EUT device under test in malfunction

Example of external fuse

Fuse in the building is designed for 32A.

A Fuse box with 16A fuse protection is installed between the building supply and the test generator.

Test generator and EUT are now fused for 16A rated current

Figure 7 - External Fusing Example

16A protection with a 100A installation with a 3-phase fuse box.

The user has protected his Equipment Under Test with this additional fuse box for a rated current of 16A.

Figure 8 - Example of External Fuse

3. Safety functions

The test area must be organized so that only those involved in the test may enter it. In the case that the safety circuit is used to control the complete area, an additional interlock contact must be used to directly protect the operator from contact with the DUT.

Neither the DUT nor any cables or accessories must be touched during the test. During work on the DUT, the test procedure must be stopped and the DUT disconnected from the power mains supply.

Coupling devices have no safety functions built in, because these functions are integrated in the generators.

3.1. Safety circuit

The safety circuit will switch off the high voltage and the TEST ON button of the unit.

3.1.1. Safety circuit for compact NX and NSG 3000A series The safety circuit locks the system and enables the generation of the high voltage impulses in the generators.

Design

Each device that has internal relevant high voltage unit, includes a safety circuit. The safety circuit works like an “open collector circuit”, where the external safety loop must be closed for switch on the high voltage.

Safety circuit closed

The device will generate high voltage pulses after start Safety circuit open

The device will switch off the high voltage and discharges the high voltage circuit

Figure 9 - Safety Circuit

Figure 10 - Safety Circuit Diagram

3.1.2. Safety circuit on Rack Systems

Rack Systems have a separate safety circuit, driven by the mains supply voltage.

Release the Safety Circuit button will disconnect the mains power from the devices and EUT supply.

For power on it is necessary to unlock the red colored safety button manually by turning.

Figure 11 - Rack Stop Button

National Standards for safety circuits can differ from the example above.

The user is responsible for the correct design of his safety circuit.

Important for operation

Connect the delivered Safety Circuit Terminal SCT or the optional Safety Circuit Adapter SCC AD to the SYSLINK plug.

The generator does not start any test if the safety circuit is not connected and closed.

NOTE: The short circuit is already short-circuited at the delivered Safety circuit terminal SCT and Safety Circuit Adapter SCC AD

. Figure 12 - Safety and

Warning Lamp Connectors

SCT Safety Circuit termination

The safety circuit terminal SCT is part of the delivery and includes the short circuit for the safety circuit. If an external safety circuit is required, please order the optional Safety Circuit Adapter SCC AD.

Figure 13 - SCC AD option for external safety circuit loop

Figure 14 - Safety Termination

3.2. Warning lamp

3.2.1. Warning lamp for compact NX and NSG 3000A series The warning lamp offers a voltage free contact that indicates the status of the generator system.

Design

Each device with warning lamp function can short thewarning lamp contact. An external powered relays max. 60 V / 2 A is controlling the lamp. The user is responsible for the warning lamp power supply

Warning Lamp switch closed (red):

- Safety circuit is closed and TEST ON is on Status: RED Lamp, Power on EUT output,

High voltage can be “switched ON”

Warning Lamp switch opened (green):

- Safety circuit is open and / or TEST ON is off - Generator is switched off

Status: GREEN Lamp, no danger, High voltage is off

Figure 15 - Warning Lamp Connection

3.3. Earthing of devices Earth Bolt

Generators must be grounded to the reference ground plane. Generally, the generators are equipped with an aluminum earth bolt (8x30mm) at the rear side of the device.

For contact the earth bolt there are the following connections:

- Screw M4 x 12 mm tapped hole

- Ø 4mm x 20mm holes for 4mm banana plugs The drawing shows the dimensioning of the earth bolt.

Figure 16 - Earth Connection Earth connection with a tress

The earth connection must be designed as a low ohmic and low inductance connection as illustrated as example in the picture at the right side.

This solution allows the user for fast exchange the device.

Figure 17 - Earth Connection Tress

Earth connection with a brass bar

Alternative method is using a brass bar equipped with banana plugs and additional fixed with a M4 screw as illustrated at the right-side picture.

This is a solution preferred for fix mounted test setup installation.

Figure 18 - Earth with Brass Bar

3.4. FI Fault current protection

The standards recommend decoupling and filter capacitors to PE for decoupling surge pulses. This is the reason for tripping fault current protection relays interrupt the mains to the EUT supply. For eliminate the circumstance use one of the following options:

Remove the fault current protection

This solution does not limit the current to PE. The surge test as other EMC tests with higher currents to PE are possible. The user must take care to the circuit with no fault current protection. Only trained professional people are allowed to perform such tests.

Using of insulating transformers

An insulating transformer separates the circuit from the protected path. The synchronization works between line and PE and therefore a connection between neutral and PE is necessary. Without this connection the stray capacitance defines the phase sync.

Figure 19 - Example with Insulating Transformers

Behind the insulating transformer the neutral and PE must be connected for a proper phase synchronization of the generator.

In case of a 3-phase system the user must perform similar.

4. Testing and Precautions

All tests offered by High Voltage or EMC generators are immunity tests on electronic equipment or devices. These tests are potentially dangerous to the operator. It is the responsibility of the user to avoid critical failures and risks to the environment and the operator.

National and International regulations regarding human safety must be followed.

Individuals with certain health conditions (e.g. with a heart pacemakers or similar devices), should not participate in testing.

Long power supply lines to the EUT may radiate energy which may interfere with other instruments unrelated to the generator.

It is the responsibility of the user to determine whether to conduct immunity tests in a given area.

Generator and coupling/decoupling voltage power supplies must be grounded and connected to reference plane.

4.1. Precautions to be taken

• EMC and High Voltage test areas must always be supplied by a decoupled and well-known power supply.

• The decoupling can be realized either by - filtering

- or the use of an isolating transformer

• When using isolating transformers, the fault current safety devices normally don’t trip.

• EMC and High Voltage test areas must always have a clear grounding strategy. All coupling/decoupling high power voltages and all LISN’s must be strictly and securely connected to the ground reference plane of the test setup.

• Please ensure the correct current back flow to the generator. Missing connections can cause extremely high voltages and may become a health hazard. Therefore, it is absolutely necessary to use ground reference planes which are connected to a protective ground.

4.2. Failures and Heavy Strain

If it is determined that a safe operation of the equipment due to failure or heavy strain is no longer possible, the supply voltage must be disconnected, and the equipment protected from unintentional use.

Unsafe operation is determined as follows:

• the equipment shows visible damage

• the equipment is not working

• the equipment has experienced severe stress during transport

• the equipment was stored in an unsuitable environment for an extended period of time.

Please exercise good judgement in determining whether a device is unsafe for operation.

4.3. Coupling Networks

• The coupling network has mostly no On / Off switch and no internal fuse for the EUT power supply. This is caused the different regulation in each country. The device under test must be protected by the user in an adequate safe solution. As an option special adapters and switches can be built in, but the user must specify this special solutions.

• Generators and coupling devices must be grounded and connected to the reference ground.

• For coupling pulses to the lines, the coupling path must be setted.

• If a line has not to be coupled, it is necessary to disconnect or switch off this coupling path.

• Special safety adapter cables are part of the delivery.

4.4. Interference to the environment

The AMETEK CTS interferences generators are instruments with a functionally emission of electromagnetic interference during the test (e.g., ESD, EFT, conducted RF, etc.). Therefore, a disturbance of the environment cannot be excluded.

The user has an obligation to use a suitable test environment in order to minimize influences to the environment. This may require a suitable screening or to test in a shielded room.

Next should be considered during the test, that nearby are no disturbers such as (switching relays or

drives with frequency converters etc.) that can influence through their emission the test.

5. Testing

The generator can be operated locally from the front panel or remotely from the computer.

When it is necessary to observe the EUT during the test, it can be more comfortable to operate locally. The tester is nearer to the EUT and therefore faster to switch off the test generator in EUT fail condition.

When the computer fails, the Test On button on the generator front or the Fail 1 input must be used for switching off the test.

5.1. Safety Precautions

• The test area must be secured that only authorized test personnel may enter it.

• Working alone with high voltages is dangerous.

• The high voltages must be switched off when nobody is present.

• Neither the EUT nor cables or accessories must be touched during the test.

• Make sure all high voltage connections are adequately taped or otherwise insulated to prevent accidental contact by you or neighboring colleagues.

• Keep one hand in your pocket when probing high voltage circuits or discharging capacitors. This reduces the peril to touch the high voltage with both hands.

• While working on the EUT, the test procedure should be stopped and the EUT disconnected from the voltage power supply.

• The EUT must be tested within a safety container or within a protected area. In extreme circumstances the EUT may ignite or explode as a result of internal damage.

5.2. Danger from EUT

CAUTION

The device being tested may become defective and ignite due to the influence of the applied test signal.

The storraged energy inside the test simulator must be to consider. This energy can destroy or damage the EUT even when the EUT operates under normal conditions.

Therefore, the operator shall take the following precautions:

• As soon as the EUT ceases to operate as intended, the test shall be stopped immediately.

• In case of internal damage, the operator may be exposed to high frequency signals of high power (up to 75 Watts and more) anywhere on the EUT.

• Cables and connectors can be overloaded by high voltages or energies.

• Due to internal damage of components fire and/or explosion may occur.

• Unintended use of the EUT may cause hazardous situations in the vicinity of the test area.

• The user is responsible for the correct EUT protection. The device under test is to be secured in such a way that no dangerous conditions arise.

CAUTION

Never touch the EUT or anything connected to the EUT during a test

It is absolutely necessary to observe and comply with all safety instructions.

National regulations in installation and operation of electrical equipment must be respected.

CAUTION

The compact NX / NSG 3000A test system is not suitable for use in an explosive atmosphere.

CAUTION

Connect the EUT only after the initial system setup has finished.

6.3.1. Qualifications of the staff

Knowledge of electrical engineering and electromagnetic compatibility is required to install the unit. The national regulations for installation of electrical equipment as well as the safety at work of electrical equipment must be known to the user.

6.3.2. Installation

The test system conforms to protection class 1. Local installation regulations must be respected to ensure the safe flow of leakage currents.

CAUTION

Operation without a ground connection is forbidden!

Two independent ground connections are necessary - one for the test system and one for the EUT. These must be connected back to the local permanent installation or to a fixed, permanent ground conductor.

Operate the equipment only in dry surroundings. Any condensation that occurs must be allowed to evaporate before putting the equipment into operation. Do not exceed the permissible ambient temperature or humidity levels. Use only officially approved connectors and accessory items.

Ensure that a reliable return path for the interference current is provided between the EUT and the generator. The ground reference plane and the ground connections to the instruments, as described in the relevant test standards, serve this purpose well.

The test system may only be opened by a qualified specialist upon specific instruction given by the manufacturer. The equipment works, on principle, with two independent power supplies, one for the generator and one for the EUT. The generator must be disconnected from both sources before any modifications to the test setup are undertaken. Besides the mains connections themselves, certain components also operate at high voltages, and are not provided with any form of extra protection against accidental contact.

The system complies with the safety requirements of IEC/EN 61010-1 (Safety requirements for electrical equipment for measurement, control and laboratory use).

It is the user’s responsibility to ensure that the test rig does not emit excessive electromagnetic interference (EMI) that might affect other equipment. The test system itself does not produce any excessive radiation; however, the injection of interference pulses into the EUT can result in the device and/or its associated cables radiating EMI. To avoid radiating unwanted

interference the standards organizations recommend that the test setup be located in a Faraday cage.

Since the purpose of the test system is to produce interference signals for interference immunity testing, the requirements in

the IEC/EN 61000 series concerning limiting the radiated EMI can only be complied with by operating the test system inside a

Faraday cage.

6.4. Installation of the compact NX / NSG 3000A

6.4.1. Installation site

Place the test system so that there is enough free space around the cooling air inlets on both sides and behind the fan outlet on the rear panel.

6.4.2. Voltage free switching

Make sure that the cables can be connected without hindrance and disconnected without problems.

The complete voltage disconnection from the device is carried out by disconnecting the cables. Make sure that capacitors inside the device can still be under voltage, even in an emergency.

6.4.3. Grounding and power connection

Two independent ground connections are necessary- one for the test system and one for the EUT. These must be connected back to the local permanent installation or to a fixed, permanent ground conductor. To avoid electric shock the power cord protective grounding conductor must be connected to ground.

Figure 20 - Grounding and power connection System GND

The system is connected to GND via the earth wire of the connected mains power cable for the generator and the EUT supply. A separate GND wire from the reference GND plane to the building earth point may be useful to avoid interferences to other areas.

EUT GND

Ensure that a reliable return path for the interference current is provided between the EUT and the generator. The GND wire from the generator to the reference GND and must be designed as a low inductance connection suitable for high frequencies.

The reference ground plane and the ground connections to the instruments, as described in the relevant test standards, serve this purpose well.

Protection (optional)

A proposal is to separate protection of the EMC system with filters, insulation transformer or fault current protection and other measures may be useful for the EMC installation. The advantage is the separation of the EMC system from all other

installation.

A shielded room with adequate filters may be the best solution for avoid unwanted conducted and radiated interference to other areas.

6.4.4. Mains Switch and fuse

The mains power voltage indicated on the instrument must correspond with the local supply voltage (mains voltage: 85–265 Vac, universal power unit, mains frequency: 50–60 Hz). Use cables of sufficient current capacity.

Figure 21 - Mains Switch, fuse holder and power input

To replace a fuse:

1) Disconnect the mains cable

2) Pull the fuse holder out of the connector 3) Remove the damaged fuse(s)

4) Insert 1 or 2 fuses (4 A / 115V and 2 A / 230 V slow blow) 5) Replace the fuse holder

6) Plug the mains cable into a power outlet with a solid ground connection

7) Switch the system on and operate as instructed in this manual

6.4.5. Connecting the generator to the ground reference

The earth connection to the GRP should be low inductive and low ohmic. The cross-section of the earth connection should be at least 6 mm2. A braid of stranded wire or a flat copper or brass strip is better.

Figure 22 - Connection to reference ground

Connection to reference ground

For burst tests, the generator must be placed on a ground reference plane which is connected to ground.

A low inductive high frequency ground connection between the test system and the ground reference plane (GRP) is absolutely essential for performing burst tests correctly.

Distance: 10.1 mm x 11 mm

Plug: Banana plug, ∅ 4 mm

6.5. Fuses for EUT with smaller nominal currents

The AMETEK CTS pulse generators have no built-in fuse for the EUT power supply. It is in the scope of responsibility of the user to protect the EUT external for the rated current.

CAUTION

The design of the external fuse must be match the following rules:

Fuse must be equal or smaller than the rated EUT current of the connected test generator Fuse must be designed for protect the connected EUT device under test in malfunction

Example of external circuit breaker

Circuit breakers in the building are designed for 32 A. A circuit breaker box with 16 A protection is installed between the building supply and the test generator.

Test generator and EUT are now fused for 16 A rated current

Figure 24 - External Circuit Breaker 6.6. EUT power ON/OFF with supply Line to Line (400V)

CAUTION

To operate the generator internal CDN with line to line voltages of 400 V, the generator must be designed for this higher line to line voltage

The internal electrical switch interrupts the power on line L. Using a two-phase supply (L-L), the second line is connected to the Neutral EUT path and can’t be interrupted by the generator. The following setup with an external contactor will interrupt both lines L1 and L2 (connected to N-path). It is controlled via the potential-free contact of the warning lamp.

The design and installation of the contactor is in the responsibility of the user.

The phase indication shows the correct connection of the supply to Phase and Neutral input of the compact NX . For the generator hardware, both, L and N paths are potential free and a reverse connection is not relevant for the generator operation. It is in the responsibility of the user to decide to run the test in correct phase-neutral connection. Anyway, with wrong phase connection it is possible and normal to measure a voltage between neutral and earth.

8.3. Connecting coupling NX with compact NX generator

When setting up the test national and international regulations regarding human safety have to be guaranteed.

Figure 34 - Adding coupling

All units, the surge generator, the EFT and the coupling matrix can be installed one above the other.

The coupling matrix should be used as central output for the EUT and should be mounted directly onto the ground reference plane.

The compact NX5 has to be mounted directly above the coupling NX5 due to the short HV cable.

It is recommended to connect the simulator to the ground reference plane of the test set-up.

The test generator realizes that a three phase coupler is connected and shows the possible coupling modes in the display of the generator. The complete system is controlled by the generator from front panel or software.

If the external coupling network is connected or switched on later than the generator, the generator must be reset by switching power ON/OFF.

On the front panel of the coupler the user can switch ON/OFF the power supply of the EUT.

Using iec.control software the coupling matrix is completely controlled by software.

Coupling device detection

After power ON the compact NX, the controller searches all external devices.

9.9. Test setup for 10/700 µs impulses

Due to the nature of the wiring used for unshielded outdoor symmetrical communication lines (twisted pairs), the coupling is always in common mode.

The coupling decoupling schematic is shown in Figure A.4. (IEC 61000-4-5 Ed 3.0)

Coupling via arrestors(GDT) or Avalanche breaking diodes (ABD) is the preferred coupling method for unshielded outdoor symmetrical communication lines. The coupling network also has the task of splitting the surge current into multiple pairs in multi-conductor cables. The internal generator matching resistor Rm2 (25 Ω) is replaced by the Rc = 25 Ω in the DCD coupling / decoupling network.
